Answer:
A. 0.52
Step-by-step explanation:
Let D be the event that person used Debit card and C b the event that person used coupon.
We have to find the probability of customer does not use coupons given that a customer does not pay with a debit card,
P(C'/D')=P(C')P(D'/C')/[P(C')P(D'/C')+P(D')P(D'/C')]
We are given that P(D)=0.35, P(C)=0.30 and P(D/C)=0.5.
P(D')=1-0.35=0.65
P(C')=1-0.3=0.7
P(D'/C')=0.5.
P(C'/D')=0.7(0.5)/[0.7(0.5)+0.65(0.5)]
P(C'/D')=0.35/[0.35+0.325]
P(C'/D')=0.35/[0.35+0.325]
P(C'/D')=0.35/0.675
P(C'/D')=0.5185=0.52
Thus, the probability of customer does not use coupons given that a customer does not pay with a debit card is 0.52.
<span>Juanita
is watering her lawn using the water that is stored by rainwater.
=> the water in the tank drops 1/3 inch in every 10 minutes she waters.
=> The tanks water level is 4 feet.
Question : Number of days can Juanita waters is she waters 15 minutes per day.
=> 4 feet is the total amount of water = 1 ft = 12 inches
=> 48 inches in total
=> 1/3 inch is used every 10 minutes = 0.33 inches
=> she waters 15 minutes per day = 0.495 inches in every 15 minutes
Solution
=> 48 inches / 0.495 inches per day
=> 96.97
So Juanita can use all the water in water tank for approximately 97 days.</span>
